Why You’re Not Sleeping—And What You Can Do About It

If you find yourself tossing and turning at night, you’re not alone. Poor sleep often starts quietly — a few restless nights here and there — but over time it can turn into a pattern that affects your mood, energy, and overall health. While it may not seem serious at first, consistently missing out on quality sleep can take a real toll on both your body and mind.

“Sleep is not a luxury,” says Winston Lai DO, family medicine physician at PIH Health. “It’s a basic biological need, just like nutrition and physical activity. When sleep suffers, nearly every system in the body feels the impact.”

What’s Getting in the Way of Your Sleep?

There are many reasons sleep becomes disrupted, and stress is one of the most common. When your brain stays in “go” mode, it’s hard to power down at night. Worries about work, family, finances, or health can keep your thoughts racing long after your head hits the pillow.

“Stress triggers the release of hormones that keep the body alert,” explains Dr. Lai. “If your mind doesn’t get a chance to slow down, falling — and staying — asleep becomes much harder.”

Daily habits can also interfere with rest. Screen time right before bed exposes your eyes to blue light, which can disrupt your body’s internal clock and suppress melatonin, the hormone that helps you feel sleepy. Caffeine late in the day or alcohol in the evening may also sabotage sleep, even if alcohol initially makes you feel drowsy.

Your sleep environment matters, too. A bedroom that’s too bright, too warm, or noisy can prevent your brain from fully relaxing. Your body needs the right signals to understand it’s time to sleep. Light, noise, and temperature all play a role in that message.

Physical conditions may also be part of the problem. Sleep apnea, acid reflux, chronic pain, or frequent nighttime bathroom trips can interrupt rest. Hormonal changes, such as those during menopause, may trigger night sweats or hot flashes that make sleep more difficult.

Simple Changes That Can Make a Big Difference

The good news is that improving sleep often starts with small, manageable adjustments:

Stick to a consistent sleep schedule.

Consistency is one of the most powerful tools for better sleep. Going to bed and waking up at the same time each day helps regulate your internal clock.

Create a calming bedtime routine.

Repeating the same relaxing activities each night signals your brain to slow down. Reading, gentle stretching, or deep breathing can help. Keeping screens out of your bedtime routine gives your mind a chance to truly unwind.

Make your bedroom sleep-friendly.

A cool, dark, quiet room supports deeper sleep. Blackout curtains, a fan, or a white noise machine can help minimize disruptions. If your mattress or pillows are uncomfortable, upgrading them can make a noticeable difference.

Watch what you eat and drink.

Caffeine can linger in your system for hours, so try to avoid it later in the day. Alcohol may help you fall asleep faster, but it often leads to lighter, less restorative sleep. Heavy meals close to bedtime can also interfere with rest.

Move your body during the day.

Regular physical activity improves sleep quality, especially when done earlier in the day. Exercise helps regulate sleep cycles, but intense workouts too close to bedtime can be stimulating.

Talk to a doctor if sleep problems persist.

If you snore loudly, wake up gasping for air, or feel exhausted no matter how long you sleep, an underlying sleep disorder may be to blame. “Persistent sleep issues aren’t something you should ignore,” Dr. Lai advises. “Your doctor can help identify the cause and find treatments that work.”

Better sleep doesn’t always happen overnight, but small changes can add up over time. By understanding what’s disrupting your rest and making thoughtful adjustments, you can begin to improve your sleep—and feel better during the day. “As your sleep improves many patients notice better focus, more energy, and even improved mood,” says Dr. Lai. “Quality sleep truly supports whole-body health.”
